To all whom `it may concern.'

Be it known that l, Liiwis l. Narnninizn a citizen of the United States, residing at Rockford, in the county of llinnebagoand State of Illinois, have invented certain new and useful improvements in Gang-Plow Frames, of which the following is a specification.

This invention relates in general to plows, and more particularly to plows which are adapted to be hitched directly to a traction engine and to be rz ised and lowered by power means carried iy the engine.

One of the primary objects of my invention is to provide a novel means by which the working depth of plows may be adjusted.

A further object is to provid/e a gang plow frame adapted to be hitched to a traction engine or any power-drawn means, to

be swung vertically and bodily from itsv tractor hit-Ch to raise and lower the plows,

A further object is to provide an iinproved construction of gang lplow frame, primarily with the view of securing simplicity and lightness of structure, and the- Fig. Z is a plan `view taken on the line of llig. l. Fig. 2l isa fragmentary plan view taken ou the line I-l-ll of Fig'. l.; and Fig..

-lis an enlarged vertical sectional view taken' on 'the line l-l of Fig.

he use of a gang of plows assoifiated to foi-iii a unit whereby they in'ay be connected to a traction engine or other power-drawn means and raised and lowered bodily as a unit. is desirable. because of the many and Vwell kinuvnatteiidant advantages of this type of gang plow. When iiiold-lioai-d plow-s are connected to draft means of thc above le.

scribed character whereby the ldraft is from a point fixed relatively to the ground. and

arc drawn alongr thil ground, the plows will shallower furrow according to the level they must seek to follow a horizontal plane. I have embodied this feature in my improvements in a manner which will be hereinafter described.

The gang' plow is' attached directly to a traction engine frame in suoli a manner that it een be swung bodily to raised and lowered positions by power-operated means carried by the tractor. rllie power-operated means for raising the gang plow I have not illustrated in the drawings, because various types of such means may be'used', and because they form no part of the subject mate ter of my present invention.

ln the drawings I have illustrated the rear end of a traction engine diagraininatically, having' shown a longitudinal frame sidebeam 5, a transverse end-beam G, and a drive-wheel 7. The side-beams 5 'carry an underliung draft .frame includinga transverse angle-bar 5l, this draft frame being' located in proximity of, but below, the driveH wheel axle.

The plows are of the nii'iid-board type and are connected as a unit to a plow frame which is pivotally connected with `the underhung draft frame in such a manner that it may be swung vertically,l being fulcrumed from said draft frame to raise andl lower the plows. For the purpose of permitting adjustment of the plows 'to different workying` depths l 'have constructed the plow frame in two relatively vertically movable longitudinally extending side bars 11 and 12 which are connected by cross-bars 13 and 14, the former 'cross-bar being located inter `mediately of the ends of the side bars and forming a pivot support` to which the rear frame section may be pivotally attached, and the latter cross-bar being rotatably mounted iii connection with said side bars at the for- .ward ends of the same and being connected as a center of oscillation, and vertically from the cross-bar 14 as an axis of oscillation. The side bars are braced tothe cross bar 13 by brace bars 16 and 17.

The rear section or plow frame proper is i constructedof a plurality of spaced longitudinallvl." extending plowbeams 18 rigidly connected at their` forward ends by cross bars 19 land braced bybars 21, and a diagonally arranged angle-beam122 ixedly connected to the rear end of said beams. This frame is interposed between the side bars 11 and 12 and is pivotally connected to the forward section through the upstanding brackets 23 fiiiedly connected to the forward end of the rear section and pivotally mounted upon the cross-bar 13. The plowbeams arev equipped with mold-board 'plows 124, and an additional number of plows may be added to the outer plow-beams 18 by exrtending said plow-beams 25 outwardly and rearwardly to osition their rear plowequipped ends 1n proper 'relation to the plows 24. From the above it will be seen that the plows'may be swung vertically as a unit, being fulcruined from the cross-bar 13 of the forward section.

The rear ends of the side bars 11 and 12 are adjustably connected with the rear section in such a manner that the forward and rear sections are maintained rigid relatively, but-the rear section may be adjusted upon its pivot, relatively to the forward section.

These functions are attained'by mounting a.-

screw-rod-26 in a nut-member 27 trunnioned at 28 uponithe rear end of each side bar portion of the'forward section, and swivelingly connecting the lower ends of the rod 26 with the rear section, Iin one instance to the anglebeam 22 as shown in Fig. 1, and in the other instance to a bracket 29 attached to an outer beam 18, as shown in Fig. 4. Each screwrod is provided with a crank-handle 31,

which when rotated will move the plows o/t' the rear section either up or down relatively to their pivotal connection with the forward section. It will be manifest that with the plows resting upon the ground, there is required but little force to turn the cranks 31,

because of the arrangement of. the several pivotal points of the frame sections.

The power-operated means above menitioned, Ifor raising the plows,'ma.y be connected to the plow frame in any suitable manner, and suitable means may be connected thereto and to the plow frame for A raisingv and lowering the plows, the latter means herein employed being that of a lever or raising-boom 32 pivotally mounted at 38 on the rear end of the tractor and connected to the plow frame by an adjustable chain 34, and bars 35 connected to the angle-beam 22. 75 The lever or boom is swung upon its pivot by the action of said powermeans, through-the agency of the intermediate lever members 36. The plows are shown in Fig. 1 in a low ered working position, wherein the depth of go the urrow's is determined by the relative position of the plow-bottoms with the point of draft. The draft being from the cross-bar 151 which is held at a position fixed relatively to the ground, the plows will'assume vg5 a'working depth as shown, with their'bb toms in a horizontal plane It willbe manifest that by turning the cranks 31 the plows may be raised or lowered relatively to the yforward section by swinging of the rear section vertically'upon its fulcrum 13, and that this movement of Athe plows changes'the vertical relation of their bottoms withthe point of draft, thereby causing the plows to turn a said adjustment by the cranks.

It will be noticed that the above described plow-carrying -frame and the arrangement of the plows gives a very simple gang' plow structure, one which is of light Weight to facilitate moving to its several positions, and one which is capable of various desired movements.

While I have shown and described a pre.- ferred embodiment of the invention, I dognot desire to limit myself to the specific embodiment shown, since various changes in structural details may be resorted to without 'departing from thev spirit of the inventionor sacrificing any of its material advantages.

I claim as ,myinventiont 1.
